I just tried some uninstalls and reinstalls of the plugins, and it did not change the firefox behavior, but it did break the way my Opera was working so that now I cannot use it on Rhapsody Online anymore. I recomment, at this point, if you have Opera working, ignore Firefox. It obviously is not well supported on 64bit. I hope I don't have too much to do to get my Opera back working on 64bit Ubuntu. It is a far better user experience anyway.
